We have a standard Thetford toilet in our nexus 28p. The ball valve flap does not open or close when the foot pedal is depressed. It is not stuck in any way. It is out of warranty. My question is should we just replace the parts needed or just replace the entire toilet? Entire toilet is about $175 and can be bought any time online or in store. Parts would need to be ordered and take time, but would avoid having to dismantle plumbing. Any advice appreciated. Thank you.

Are parts available from any RV dealer? Many parts can be ordered over night on a special order. My other question would be if some toilets are more popular so parts are available without ordering or is there another brand that is better quality? Maybe others have had experience with issue. I have a Thetford myself so also interested.

After spending a lot replacing the pedal and ball it starting leaking all over again - For about $150 plus labor to install it I got a Dometic 310 put inI like it because with multiple water outlets around the rim it cleans the sides better In addition it is designed to leave more water in the bowl - this reduces buildup on the bowl and reduces odors

ours broke one time years back, I pulled the commode and put on old cloths and rubber gloves , and took it aprt about an hour you can rebuild the hole thing, get your kit on line and do it.

There comes a point where you can buy parts, or just pull the pooper and upgrade. This is quite subjective. The nice thing about a complete toilet upgrade is that it is under warranty, so any subsequent breakages are covered for a period of time.

Would I have to also order Dometic parts on line? I like what was said about Dometic leaving more water in the bowl. I have replaced my Thetford bowl seal twice and it is only 2 years old. Does Dometic bowl seals hold up better?

Amazon.com has Thetford toilets & Thetford toilet parts. I used them when my valve got cracked from being frozen during winter storage. Dick
